      Server Description

      A memory-optimized instance featuring ninety-six virtual cores and 768 GB of RAM for high-throughput database and caching workloads.

      Memory Optimized

      Amazon Web Services r5.24xlarge is a memory-optimized instance utilizing the AWS Nitro hypervisor and an x86_64 Intel Xeon 8259CL processor. It is configured with 96 vCPUs, 48 physical cores, and 768.0 GB of DDR4 memory, yielding a 1:8 vCPU-to-RAM ratio. The instance lacks local storage and GPUs but delivers a baseline network bandwidth of 25 Gbps. Performance benchmarks show strong multi-core capabilities, with a PassMark CPU score of 55744.75, and exceptional memory bandwidth, reaching 220.3 GB/sec for uncached large-block reads. It also demonstrates high efficiency in database operations, executing 74.62 million Redis SET operations per second. However, single-core performance remains a tradeoff, with a stress-ng single-core score in the bottom 25%. This instance is highly suited for memory-intensive workloads, including large-scale in-memory databases, caching layers, and high-throughput data processing.

      Workload Profiles

      2.88Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
